Archaic period (North America)

In the classification of the archaeological cultures of North America, the Archaic period or "Meso-Indian period" in North America, accepted to be from around 8000 to 1000 BC in the sequence of North American pre-Columbian cultural stages, is a period defined by the archaic stage of cultural development. The rest of the Americas also have an Archaic Period. The Archaic stage is characterized by subsistence economies supported through the exploitation of nuts, seeds, and shellfish. As its ending is defined by the adoption of sedentary farming, this date can vary significantly across the Americas.

This classification system was first proposed by Gordon Willey and Philip Phillips in the widely accepted 1958 book Method and Theory in American Archaeology.

In the organization of the system, the Archaic period followed the Lithic stage and is superseded by the Formative stage.

Numerous local variations have been identified within the cultural rankings. The period has been subdivided by region and then time. For instance, the Archaic Southwest tradition is subdivided into the Dieguito-Pinto, Oshara, Cochise and Chihuahua cultures.

Since the 1990s, secure dating of multiple Middle Archaic sites in northern Louisiana, Mississippi and Florida have challenged traditional models of development, as hunter-gatherer societies in the Lower Mississippi Valley organized to build monumental mound complexes as early as 3500 BC (confirmed at Watson Brake), with building continuing over a period of 500 years. Such early mound sites as Frenchman's Bend and Hedgepeth were of this time period; all were localized societies. Watson Brake is now considered the oldest mound complex in the Americas, preceding that built at Poverty Point (both are in northern Louisiana) by nearly 2,000 years. More than 100 sites have been identified as associated with the regional Poverty Point culture of the Late Archaic period, and it was part of a regional trading network across the Southeast.
